1. WRAP 2002 Fire Emissions Inventory Inter-RPO Fire and Smoke Technical and Policy Coordination Meeting February 9-10, 2005 – Round Rock, TX Dave Randall (303.988.2960 x221; drandall@airsci.com) Air Sciences Inc. (www.airsci.com) 1301 Washington Ave, Suite 200 Golden, CO 80401

2. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI2 WRAP 2002 Fire EIs Modeling Evaluation Emission Inventory. –Actual 2002 wildland fire and prescribed fire emission inventories. –Use of the 2018 Agricultural Burning Base Smoke Management Program emission inventory with State & Tribal outreach and QC. –Primary uses: to verify and enhance dispersion model performance to test geographic source apportionment (modeling estimates of contribution at each Class I area from each upwind source jurisdiction).

3. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI3 WRAP Fire – Technical Approach In general, 2002 technical methods consistent with the 1996 historic emission inventory. *NEW* Historic EI for Wildfire (WF) and Prescribed Burning (Rx) were produced. FEJF’s 2018 Agricultural Burning (Base Smoke Management) with State/Tribe outreach and QC Brief run-down of technical methods follows.

4. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI4 Data Quality Objectives A specific location for each fire event. A specific calendar day in 2002 for each fire event. A specific size for each fire event. Sufficient information to use supplied data or assign a fuel loading for each fire event.

5. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI5 Activity Data - Wildfire > 10 Acres NIFC – National Situation Report and ICS-209 Datasets were merged DOI’s Fire Management Data and USDA – FS’s National Interagency Fire Management Integrated Database were appended. Natl Situation Report/ICS-209 records supplemented on a record-by-record basis location, size, and fuel loading info.

6. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI6 Activity Data – Prescribed Fire No de minimis size cut-off Data requests out to State AQ and/or Forestry Departments…data rec’d from all states in the WRAP region. Rx fire data (DOI-1202; NIFPORS, FASTRACS) also received from federal agencies Effort to reconcile/augment state data with federal data

7. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI7 GIS Data Augmentation & QC Geo-referencing Fire Location by TRS & County GIS-based fuel loading assignments State & County Identifiers GIS QC techniques –Locations match with state/county identifier –Locations don’t fall in water/urban areas

8. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI8 GIS Data Augmentation & QC Complex fire identification and QC Large fire refinements Detailed activity data QC notebooks of WF, WFU, and Rx burning out to States (13), Tribes (8), and Federal Land Managers (approx. 60) for detailed QC review and input.

9. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI9 Fuel Loading & Emission Factors Fuel Loading –Explicit fuel loading/consumption data used if supplied in activity data. –Modified NFDRS (to include duff & crown fuels) for WF & Rx fire Emission Factors (AP-42 & OAQPS report) –Wildfire and Rx Broadcast Burns –Rx Pile Burns TSP; PM10; PM2.5; EC; OC; VOC; CH4; NH3; NOx; CO; SO2; PM-coarse

10. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI10 Other Technical Steps Daily fire growth for multi-day events –WF – only multi-day events >100 acres (“escapability size”) were allocated to daily events “spreading oval” geometric fire growth (from FEPS) over first 2/3 of the duration provided –RX – total acres / no. of days Smoldering emissions added. Plume profile assignments (based on heat release and buoyant efficiencies) –Look-up tables, and *virtual acres* used to assign PTOP, PBOT, LAY1F PBOT increased from 1996; LAY1F adjusted from 1996 by 38/80

11. Inter-RPO Mtg, Austin, TX WRAP 2002 Fire EI11 Deliverables/Data bins –PT Files (formatted for the Sparse Matrix Operator Kernel Emissions “SMOKE” modeling system) PTINV – general event information PTDAY – daily emissions of each pollutant PTHOUR – hourly plume profile assignments –National Emissions Inventory NIF format –WRAP’s Emissions Data Management System (EDMS)
